How to Charge JBL Flip 4 Wireless Bluetooth Speakers




You can charge JBL Flip 4 wireless speakers conveniently via their hidden USB charge ports.  To summarize: First, select an adequate USB power adapter.  Why this?  Because the Flip 4 does not come with this as a standard accessory.



Plus, the Flip 4 needs a high power USB power source to charge fully in a reasonable amount of time.  Next, connect the orange micro USB cable between the Flip 4 and that adapter.  Next, plug the adapter into a working wall outlet.  Finally after a few to four hours, your JBL speaker will fully charge, and you’ll be able to play it again for up to twelve hours before you must charge it again.

At least one of the battery status lamps lights up on the Flip 4 when you apply enough USB power.  There are five lamps that light in succession as the speaker battery charging progresses, as shown in the next picture.

6. Let the Flip 4 Charge Until All Battery Power Lights Go Out

Battery charging is complete when all but the last of the battery status lights light solid.  The last one continues to blink for several minutes.

This next picture shows the speaker just before completing a full charge cycle. Note that all the lamps in the battery status gage are glowing.  However, the last one continues to blink.

8. Fully Close the Waterproof Port Door

Note that unless this flap is snapped securely and completely in place, water could enter the port area, possibly damaging the Flip 4 electronics inside.  So, be sure to press the port door closed with enough force to properly seat it, for full water resistance.

9. Done!

We have now fully charged our JBL Flip 4 wireless Bluetooth speaker.  Note that the battery charge status gage just after turning on the Flip 4 after a full recharge.  All lamps are aglow, meaning that the speaker is current fully charged.

Repeat this process every ten to twelve hours of music play through the Flip 4, to keep its battery in top condition. We charge ours when the battery status gage lights show only one light glowing.
